QPR were also fined £875,000 after being found guilty of two of the seven charges against them relating to the ownership of Argentine midfielder Alejandro Faurlin.

However, Stuart Gilhooly, a leading football solicitor, described the 99.5% "conviction" rate as "extraordinary".

With none of those 471 cases being overturned on appeal, he said the FA's system needed urgent review.

"A body with that sort of conviction rate needs to look at its procedures," said Gilhooly, a legal representative for the Professional Footballers' Association of Ireland who has worked on a number of key cases for the Football Association of Ireland.

"It is as if you are guilty until proven innocent and that is not in the interests of justice."

I'm surprised that the figure is so high. The percentage of 'not proven' cases is negligible

By way of comparison, Crown Court conviction rates were just over 80% in 2009.

"The comparison with the public criminal law system is unfortunate, as we are not comparing apples with apples - they are fundamentally different," said the FA spokesman.

Another sports lawyer, who preferred not be named, described the FA as "police, judge and jury all rolled into one".

He added: "Your chances of success before them, Uefa and Fifa are virtually nil.

"I seldom advise clients to have a personal hearing. Sentences can be extended almost without limitation."

After banning Suarez for eight games and fining him £40,000, the FA published a 115-page report into the findings of its independent commission.

Liverpool decided not to appeal against Suarez's ban, but issued a statement saying it was their "strongly held conviction... that the Football Association and the panel it selected constructed a highly subjective case... based on an accusation that was ultimately unsubstantiated".

"I'm surprised that the figure [99.5%] is so high," said Liz Ellen, a lawyer for London-based solicitors Mishcon de Reya.

"There must be a large number of potentially provable cases [that may end in a guilty verdict] not being pursued if the FA's criteria for advancing a case is producing an almost perfect record."

The statistics also do not take into account the 'no further action' cases the FA has reviewed.

"I'd estimate we look at thousands of cases in a year that we don't take any action over," added the FA spokesman.

"The counter argument is that, if we were bringing charges but not being successful in doing so, that we are wasting people's valuable time, wasting the game's money and not doing our job properly."

After the new year fixtures the FA looked at Warnock's and Barton's media comments following the latter's sending-off against Norwich - as well as Arsenal manager against Fulham. It took no action in all instances.

The FA's disciplinary panels are made up of three people - a chairman from the FA's panel, someone else who has played or managed within the professional game, and a third person from the FA Council, who has considerable experience in the game.

In the Suarez case, the FA used one of the country's leading criminal lawyers, Paul Greaney QC, with assistance from Dario Giovanelli of the FA. The chairman of the Sheffield & Hallamshire FA Brian Jones and former Sunderland manager Denis Smith were also on the panel.

But Gilhooly questioned whether the FA's appointment system created "fairness".

LIES, DAMNED LIES & STATISTICS?

Of the 471 cases, not all resulted in a direct sanction - with some involving warnings over future conduct or suspended sentences to act as a deterrent.

Many of those would also have been accepted charges, but with a plea to mitigate on paper or in person in relation to the sanction

"I'm never happy where a body is appointing the judge and the prosecutor. You never see that in a court environment," said Gilhooly, who is a self-confessed Liverpool fan.

Despite the FA's high conviction rate, Ellen urged clubs not to be deterred from challenging charges.

She added: "Even where a charge is proven there is a wide range of sanctions available to the disciplinary panel.

"Therefore, where they feel aggrieved, clubs, players and managers should take the opportunity to put their case forward as this could reduce the sanction from a fine or suspension down to a warning as to future conduct."
